 wherein the sub door comprises:
 an outer plate that defines a first opening, 
 a door liner that defines a second opening facing the first opening, 
 a panel assembly that covers the first opening and the second opening, and 
 an outer bracket that connects the panel assembly to the outer plate, and 
 
 wherein the second display is coupled to the outer bracket. 
 
     
     
       2. The refrigerator of  claim 1 , wherein the second display is configured to be turned on based on the first display being turned on. 
     
     
       3. The refrigerator of  claim 2 , wherein the second display is configured to, based on the second display being turned on, turn on one or more light emitting portions among the plurality of light emitting portions. 
     
     
       4. The refrigerator of  claim 1 , wherein the plurality of light emitting portions are arranged along a line extending in a horizontal direction. 
     
     
       5. The refrigerator of  claim 1 , further comprising a speaker disposed at the cabinet or the main door and configured to operate based on the first display being turned on, and
 wherein the second display is configured to vary a light emitting pattern of the plurality of light emitting portions in accordance with an intensity of sound output from the speaker. 
 
     
     
       6. The refrigerator of  claim 5 , wherein the second display is configured to, in a state in which the speaker does not operate, maintain the light emitting pattern of the plurality of light emitting portions. 
     
     
       7. The refrigerator of  claim 5 , wherein the second display is configured to vary a number of light emitting portions to be turned on among the plurality of light emitting portions in accordance with the intensity of the sound. 
     
     
       8. The refrigerator of  claim 7 , wherein the second display is configured to increase the number of the light emitting portions to be turned on based on an increase of the intensity of the sound. 
     
     
       9. The refrigerator of  claim 5 , wherein the second display is configured to vary a color of each of the light emitting portions to be turned on in accordance with the intensity of the sound. 
     
     
       10. The refrigerator of  claim 5 , wherein the second display is configured to vary a luminous intensity of each of the light emitting portions to be turned on in accordance with the intensity of the sound. 
     
     
       11. The refrigerator of  claim 5 , wherein the second display is configured to, based on the intensity of the sound corresponding to a first level, turn on a predetermined number of light emitting portions among the plurality of light emitting portions, the predetermined number of light emitting portions comprising a first number of light emitting portions that emit light in a first color and a second number of light emitting portions that emit light in a second color different from the first color. 
     
     
       12. The refrigerator of  claim 11 , wherein the second display is configured to, based on the intensity of the sound corresponding to a second level greater than the first level, vary the first number of the light emitting portions and the second number of the light emitting portions. 
     
     
       13. The refrigerator of  claim 5 , wherein the second display is configured to vary a position of each of the light emitting portions to be turned on in accordance with the intensity of the sound. 
     
     
       14. The refrigerator of  claim 1 , wherein the second display is disposed between the first display and a lower end of the main door. 
     
     
       15. The refrigerator of  claim 1 , wherein
 the outer bracket is disposed to surround the panel assembly. 
 
     
     
       16. The refrigerator of  claim 1 , wherein the outer bracket is provided with an installation groove. 
     
     
       17. The refrigerator of  claim 16 ,
 wherein the second display further comprises a substrate on which the plurality of light emitting portions are installed, and 
 wherein a stopper is provided on the outer bracket and is configured to, based on the substrate being inserted into the installation groove, restrict movement of the substrate. 
 
     
     
       18. The refrigerator of  claim 1 , wherein the panel assembly comprises a front panel and one or more insulating panels spaced apart from the front panel, and
 wherein the front panel comprises:
 a first area configured to transmit light, 
 a second area disposed outside the first area and configured to block light, and 
 a third area disposed between a lower end of the first area and a lower end of the front panel and configured to transmit light emitted from the plurality of light emitting portions. 
 
 
     
     
       19. The refrigerator of  claim 18 , wherein the third area is disposed between the first area and the second area, and
 wherein the plurality of light emitting portions face the third area and are disposed rearward relative to the third area. 
 
     
     
       20. The refrigerator of  claim 19 , wherein the panel assembly further comprises a diffusion sheet that is disposed between the front panel and the plurality of light emitting portions and covers a rear side of the third area or a front side of the plurality of light emitting portions. 
     
     
       21. The refrigerator of  claim 1 , wherein the panel assembly comprises:
 a front panel; 
 one or more insulating panels spaced apart from the front panel; and 
 a diffusion sheet attached to a rear surface of the front panel, and 
 wherein the outer bracket is spaced apart from the diffusion sheet.
